Types of LTM

Question 1

Who suggested that the LTM was oversimplified?

Answer 1

Tulving

Question 2

What are the sections to the LTM?

Answer 2

Tulving argued the model was to simplistic and created more sections:
Declarative:
- Episodic - recall of events in our life; like a diary, time stamped
- Semantic - shared knowledge of the world; like a dictionary, less vulnerable to distortion

Procedural - how to do things; automatic, hard to explain to others

Question 3

What are the strengths and weaknesses of the types of LTM?

Answer 3

Strengths:
- Case studies support it (HM, CW)
- Neuroimaging supports it (Buckner and Peterson)

Weaknesses:
- Case studies are ungeneralisable and unreplicable (less reliable)
- Neuroimaging is inconsistent; other brain scan studies have shown opposite results to Buckner and Peterson’s trials
